The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Mass is related to how much stuff is there and weight is related to the pull of the Earth (or any other planet) upon that stuff.

Mar 12, 2024 · Understand Newton’s second law of motion. Apply Newton’s second law to determine the weight of an object. Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion.
The effect of reduced acceleration is easy to show with a FBD of two objects that are identical except for mass and are falling through the air at the same speed. For these two objects the air resistance forces are equal, and the gravity force is greater on the heavier object.
Dec 16, 2023 · The four basic forces will be encountered in more detail as you progress through the text. The gravitational force is defined in Uniform Circular Motion and Gravitation, electric force in Electric Charge and Electric Field, magnetic force in Magnetism, and nuclear forces in Radioactivity and Nuclear Physics.

Kick a ball and it'll fly up into the air beforefalling back down to the ground. That's an example of everydayforces. What exactly is a force? Kicking a ball involves you applying a force (a push with your foot)that makes it fly upward. But once it's shooting through the air, theinvisible force of gravitypulls it back down to Earth—and that's adiff...
When we're looking at how things work or move, wetry to identify the force that's responsible. So when a flying ballzooms to the ground, we say "Aha! That's the force of gravity."But it's very rare to find only one force acting on something. Mostof the time, there are several different forces working at once, allpulling or pushing with different st...
When a force acts on an object, it often makes itmove faster or in a different direction. Once something is moving,you don't need a force to keep it moving: it will carry on moving allby itself unless another force stops it. When a rocketblasts intospace, you need a force to make it lift off to begin with and toovercome the force of Earth's gravity...
It takes a force to make something move in adifferent way, and that includes changing the direction in whichsomething is moving even if its speed stays the same. If you want tomake something go round in a circle, you have to apply a force tomake it turn and keep on applying that force to keep it turning. Thatmakes sense: something moving in a circl...
Forces make things move—but they also bringmoving things to a halt. Roll a toy car over a rug and it'll quicklycome to a standstill. The force of frictionsteals the car'senergy and slows it down. Friction is the force between two differentobjects that are in contact, either when they're locked together andtouching or when one of them slides past th...
Have you ever tried tugging the aluminum ring-pull of adrinks can and found it suddenly snaps off in your hand? What you'retrying to do is use a force to make the ring-pull move and changedirection at the same time. But instead of doing what you expect, onepart of the ring-pull snaps away from the other. This is an exampleof how forces can change a...
More generally, a force is an interaction that causes a change. Force is a vector quantity associated with an interaction. When several forces act on a system it is the net, external force that matters. Since force is a vector quantity, use geometry instead of arithmetic when combining forces.
